Fourth, blood pressure was measured in different seasons (44.6% in winter and summer vs 55.4% in spring and autumn) which made the blood pressure incomparable between participants. Fifth, it is unclear why the strength of untreated hypertension vs treated hypertension on risk of CVD mortality decreased with age increasing. The risk ratio was about 4 for participants ages 35 to 59 years, while the risk ratio was approximately 2 for participants ages 70 to 74 years. Does it mean that untreated hypertension in middle-age adults is more harmful than that in older adults? Finally, we felt that the third age group in Figure 3 might be wrong and that it should be “70-74” rather than “70-79.” Donghao Zhou, MD Shiming Wang, MD Tao Tian, MD Author Affiliations: Department of Geriatric Cardiology, Linyi People’s Hospital, Linyi, China.

In Reply We appreciate the interest in our work from Zhou and colleagues. The China Kadoorie Biobank is a large populationbased prospective cohort study of 0.5 million adults ages 35 to 74 years (when recruited during 2004-2008) from 10 diverse regions of China.1 We reported that about one-third of the participants had hypertension at recruitment, but less than 5% of these hypertensives had their blood pressure properly controlled (
